Problems solved by technology

[0003] However, since the coupling mechanism of the air chucks disclosed in Patent Document 1 and Patent Document 2 is composed of an air cylinder, and uses air to automatically replace the finger support portion, the structure is complicated and it is necessary to connect air piping
In addition, there is also a disadvantage that the air cylinder cannot be operated when air cannot be supplied during maintenance, etc., so that the finger support portion cannot be separated from the chuck body portion.
[0006] However, since the air chuck engages the hook of the snap lock with the engaging portion of the guide member outside the air chuck, the hook or engaging portion may be disengaged due to contact with a peripheral member. or damaged, the connection is very unstable

Embodiment Construction

[0055] Figure 1-Figure 7 The first embodiment of the air chuck according to the present invention is shown. This air chuck 1A has a finger support part 2 and a chuck body part 3. The finger support part 2 has a pair of finger-like 5, 5, the chuck body part 3 is built with an operating mechanism 6 for opening and closing the pair of fingers 5, 5, and the finger support part 2 and the chuck body part 3 are connected by a connecting mechanism 4 Connect in a detachable manner.

[0056] In addition, in the following explanations, up, down, front, back, left, and right are figure 1 direction shown.

[0057]The finger support part 2 has left and right elongated support rails 10 in a channel-shaped cross section, and the pair of fingers 5, 5 are moved along the guide groove 11 formed on the upper surface of the support rail 10. The support rail 10 is supported openably and closably.

[0058] The front view shape of the finger 5 is substantially T-shaped, and has a rectangular blo...

Abstract

The invention provides an air chuck, to link a finger support part easily and stably to a chuck main body part and to detach the finger support part safely and readily from the chuck main body part through a manual operation. The air chuck includes: a finger support part 2 including a pair of fingers 5; a chuck main body part 3 including an operation mechanism 6 operable to open and close the pair of fingers 5; and linking mechanisms 4 that detachably link the finger support part 2 to the chuck main body part 3. The linking mechanisms 4 each include: a linking shaft that extends from the finger support part 2; a shaft insertion hole 44 formed in a body 23 of the chuck main body part 3; a catch body 19 that becomes elastically caught on a catch surface 18a of the linking shaft when the linking shaft is inserted into the shaft insertion hole 44; and a delinking member 70 that is manually operated so as to release the catch body 19 caught on the catch surface 18a when the finger support part 2 is detached from the chuck main body part 3.

Description

technical field [0001] The present invention relates to an air chuck provided with a pair of fingers that can be opened and closed. An air chuck in which the chuck body portion of the finger is detachably connected. Background technique [0002] For example, as disclosed in Patent Document 1 to Patent Document 4, there are known pneumatic chucks in which a finger support portion and a chuck body portion are detachably coupled to each other by a coupling mechanism, and the finger support portion has A pair of fingers that can be opened and closed freely, and the chuck body has an operating mechanism for opening and closing the pair of fingers. Such an air chuck can cope with various kinds of workpieces by replacing the finger supports according to the kinds of workpieces, and thus is efficient and economical. [0003] However, since the coupling mechanism of the air chucks disclosed in Patent Document 1 and Patent Document 2 is constituted by an air cylinder and uses air to...
